Introducing Hypernate: Data Mapper Framework for Hyperledger Fabric Chaincode

Meet Hypernate: a fresh, open-source way to write JVM Fabric chaincode with less key-value boilerplate and more joy — think entities + CRUD, declarative/composite keys, safe range queries via value mappers, and a plug-and-play middleware pipeline for logging, tracing, and caching.

Repos

• LF-Decentralized-Trust-labs/hypernate
• LF-Decentralized-Trust-labs/hypernate-samples

Planned agenda

• Greetings & why we built Hypernate
• Feature tour: entities, keys, mappers, middleware
• Live coding: refactor a basic Fabric contract with Hypernate
• Run the samples & pro tips
• Roadmap & contributor Q&A

What you’ll learn

• How to model entities and do clean CRUD without fuss
• Smart key design (primary/composite, numeric pitfalls, value mappers)
• Drop-in middleware (logging, tracing, write-back caching)
• Using HypernateContract, HypernateContext, and Registry
• Running the samples locally — and how to jump in with issues/PRs

Who should attend
Fabric devs, architects, educators, and everyone interested in smart contracts :)
